## Question

###### The only force acting on a particle is conservative force $\vec{F} .$ If the particle is at point $A,$ the potential energy of the system associated with $\vec{F}$ and the particle is 40 $\mathrm{J} .$ If the particle moves from point $A$ to point $B$ , the work done on the particle by $\vec{F}$ is $+25 \mathrm{J}$ . What is the potential energy of the system with the particle at $B ?$
